Multiresidue Antibiotic Analysis
Scientists from the USDA';s Eastern Regional Research Center (Wyndmoor, Pennsylvania) analyzed 11 beta-lactam antibiotics in bovine kidney using a sample preparation method consisting of an acetonitrile-water extraction followed by a dispersive solid-phase extraction with a C18 sorbent, extract concentration, and filtration with syringeless filter vials.

The final filtered extracts were analyzed by liquid chromatography-tandem mass spectrometry. The antibiotics included amoxicillin, ampicillin, cefazolin, cephalexin, cloxacillin, DCCD, deacetylcephapirin, dicloxacillin, nafcillin, oxacillin, and penicillin G.
